xorg.log

When selecting RGB subpixel font antialising on my mothers laptop (Geforce
488Go / NV18) icons are suddenly misrendered (see screenshot)

Tried several options such as NoUploadTo/DowloadFromScreen, MigrationHeuristics
smart/greedy, agpmode=0 - however only disabling render acceleration completely
did help.

The notebook is running Fedora-20 + latest updates (linux-3.15.4), the issue
happends with nouveau 1.0.9 as well as nouveau git from 20140713.

PS: It is incredible how well nouveau performs for 2D operations these days,
thanks for working on improving this area over the past years.
